This patched copy of uTorrent removes the restrictions on torrents marked as
private, allowing uTorrent to use DHT, Peer Exchange and Local Peer Discovery 
to look for new peers when it is normally not allowed.
How it works
------------
In its internal data structures, uTorrent uses four bits in one byte of data
per torrent to record these settings.
       bit     7   6   5   4   3   2   1   0
               \           /                
                 not used                  DHT enabled  default: 1 
                 set to 0               
                                       private torrent
                                   Peer Exchange enabled  default: 1 
                               Local Peer Discovery enabled  default: 1 
When a torrent file is added, uTorrent checks the  info  section for an
integer value named  private . If it s set to 1, it marks the private torrent
bit in the byte shown above, which forces the other information in this byte
to be ignored.
This byte is also saved in the resume.dat file  a bencoded file that uTorrent
uses to save its state  as an integer value named  dht .
The patch works by storing the private torrent flag in bit 7 instead of bit 1
so that all the code in uTorrent that checks bit 1 to determine if this is a
private torrent will always find that it isn t. However, it writes the  dht 
value out to the resume.dat normally, so if you start an unpatched copy of
uTorrent your private torrents will still be private.
The extra code to do this is placed at the end of the .text segment and its
virtual size increased accordingly.
Reproducing the patch
---------------------
Here are the steps required to apply the patch; you will need UPX version 3.03
and a hex editor:
 1. Decompress the uTorrent.exe file using the following command:
     upx -d uTorrent.exe
 2. Open the uTorrent.exe file in a hex editor and change the following:
     position  old bytes                new bytes

               00 00 00 00              09 0A FB FF
 3. The digital signature is now invalid. Remove it from the file by deleting
    everything after position 8F000.
 4. Recompress the file using this command:
     upx --ultra-brute uTorrent.exe
 5. This will produce a file of size 267264 bytes. The patch is now complete
    and should be identical to the file in this torrent.
